BOM version 1.0 + cyclonedx-core-java integration

Note: the cyclonedx-core-java library has been integrated and is used to generate the BOM. So, all old model classes used so far has been removed.

First development version

This version allow to create a bom.xml from sbt shell. The file created works with tools like Dependency Track (https://dependencytrack.org/). However, the result was not validated against any version of the bom file format. Anyway, the reference version is 1.0 (http://cyclonedx.org/schema/bom/1.0).
